Natural hot springs

100% natural hot spring “Chojusen”

We hope the customers that they will live until Cho (it means a trillion in Japanese), so we name the hot spring “Chojusen”. It is a great hot spring that we pumped up from 880 meters from underground. it is alkalescent water, so it is gentle to skins and makes skins more beautiful.

And it is also effective for excessive sensitivity to cold because chloride spring that is called “Netsunoyu” has excellent moisturizing action and prevents coldness after a bath. This hot spring has salty taste, and it is said that this salt content is effective for cut, burn injury and chronic skin diseases because it enhances bactericidal effect.

Taking the hot springs twice or 3 times in a day to enhance the effect of hot spring and continuing them more than 3 days are considered ideal. Please heal your tired heart and body, view Ushikunuma and take the hot spring with taking it easy.
